Single player map recommendations
All i'm plaing currently is single player and there are so many to choose from and I'm wondering if there are any maps that you all can recommend to me. Are there any maps that are large but have choke points? I've been playing the gateway map and it's really fun to hold several AI's at bay at a single choke point for those epic defenses. What maps are out there that share this type of gameplay where there are two stars linked by one planet? I only ask because I'm new to this and i'm still learning the micromanaging and i find it easier to learn the tech tree's and overall planet deveolpement when I only have to worry about enemies coming at me from one phase lane. As much as I love the battles, I enjoy the empire building and the infrastructure and I want a map that allows me to focus on that and not so much defending 8 planets from attacks from 15 directions with varied ships fleet compositions.
Any recommendations?
